You can determine how much power you have or test it by applying your strikes to the heavy bag. This will make the force in your strikes measurable...and you will be able determine if you are gaining or losing proficiency.

Why don't you actually go and study a martial art instead of surfing the net trying to become a 'web-warrior'. Then you wouldn't ask so many silly questions and you might find some genuine answers to your questions.

The ultimate takedown move is a shotgun blast to the midsection. If you don't even have access to a heavy bag you are obviously not training in an actual fighting art. If you want to test your skill come to The Coney Island Gym and Kombat Karate Dojo, I'll help answer your question for you.
